Oops, that one should be HTTPS.  The other APT URLs must be HTTP,
sadly, APT itself gets very grumpy if one attempts to use HTTPS.

As for validating the key...sure, we can talk people through doing
that, but either it's obvious or it's voodoo, depending on the user.

What 921600 woes? :)

Seriously, that was part of the point of cryptech_miniterm.  But I
guess I can add a note warning that if one is going to use something
else that something else had better support 921600 baud.

Thanks for the review!
